A bottle believed to have contained radium was found beneath the ground near a supermarket in Setagaya Ward, Tokyo, on Tuesday in the second such discovery since high levels of radiation were detected in the area last month, officials said.
A Setagaya official said the substance inside the bottle was highly likely to be radium-226. The bottle was found buried in soil at a spot where the radiation reading reached 170 microsieverts per hour.
Radium-226 has been used for medical procedures.
